Write the equation of a line PERPENDICULAR

Mathematics
1 answer:
loris [4]2 years ago
5 0

Answer:

im pretty sure its y=1/3x

Step-by-step explanation:

rearrange for y to be subject

its perpendicular so then the gradient will be the negative reciprocal (-1 / -3= 1/3) so thats your new gradient

then when you substitute the (3,-1) into that equation get -1=1 + c so then c is 0  and your whole equation is y=1/3x

Graph: g(x)=5cos((\pi )/(2)x-(3\pi )/(2))-2
Tatiana [17]

g(x)=5cos((\pi )/(2)x-(3\pi )/(2))-2

generate by:  Amplitude:5    Period:4

                      Phase shift:(3 to the right)    Vertical shift:-2

x=3,g(x)= 3

x=4,g(x)= -2

x=5,g(x)= -5

x=6,g(x)= -2

x=7,g(x)= 3

the graph is like cos(x)
